The flexoelectricity describes the contribution of the linear couplings between the electric
polarization and strain gradient and between polarization gradient and strain to the …

Flexoelectricity—the coupling between polarization and strain gradients—is a universal
effect allowed by symmetry in all materials. Following its discovery several decades ago …

The flexoelectric effect is the response of electric polarization to a mechanical strain
gradient. It can be viewed as a higher-order effect with respect to piezoelectricity, which is …

Electromechanical effects are ubiquitous in biological and materials systems. Understanding
the fundamentals of these coupling phenomena is critical to devising next‐generation …

One of the most tantalizing applications of piezoelectricity is to harvest energy from ambient
mechanical vibrations for powering micro and nano devices. However, piezoelectricity is …

This paper presents a design methodology based on a combination of isogeometric analysis
(IGA), level set and point wise density mapping techniques for topology optimization of …

In this paper, sensitivity analysis has been applied to identify the key input parameters
influencing the energy conversion factor (ECF) of flexoelectric materials. The governing …

Flexoelectricity is a size-dependent electromechanical mechanism coupling polarization
and strain gradient. It exists in a wide variety of materials, and is most noticeable for …

The ability of certain materials to convert electrical stimuli into mechanical deformation, and
vice versa, is a prized property. Not surprisingly, applications of such so-called piezoelectric …

The ability of a material to convert electrical stimuli into mechanical deformation, ie
piezoelectricity, is a remarkable property of a rather small subset of insulating materials. The …
